Toshiba Laptop Cooling Problem
I am working on a friends older but rather high end Toshiba laptop. It starts fine and boots into windows but within 5 or so minutes it simply shuts off, not shuts down, just turns off instantly. I opened it up and found dust caked between the fan and heat sink fins. I cleaned it up and started it again and it does the same thing. So today I left it open, powered it up and inspected it while it was running. Well the CPU part of the heat pipe started getting warm and then hot and then quite hot. I felt further down the heat pipe and the pipe itself was just a bit warm. Also the cooling air coming off the fins was cool and barely even warm. So is it possible the heat pipe is not working, that certainly seems to be the case. However before I buy a replacement I was wondering if anyone has any experience with something like this. Obviously if the pipe had leaked that would be the case but I see nothing that indicates that. I don't know if the working fluid would show it it did or not. Any thoughts and experiences with something like this are welcome. Thanks.
